The Lenze AC Tech MC Series drives are built in rugged steel enclosures that hold up to daily life on the factory floor. The easy to read 16 character LCD display above the drive keypad allows for easy and intuitive set up as well as daily operation.
- 1/4 through 150HP (0.18 - 110kW)
- Input voltages from 120V single phase (with voltage doubler) to 590VAC
- NEMA Type 1, 12, 4 and 4X Enclosures
This constant horsepower drive can be set up for simple applications requiring ramped start, ramped stop and speed control to demanding applications that require PID set-point control and many other functions. The MC Series consists of the MC1000 and MC3000 models; most applications will use the MC1000 with a keypad that includes Start, Stop, up, down, forward/reverse, Program/Run, Auto/Manual and Enter buttons. For non-reversing applications that require independent switching of start and stop from local to remote and speed control from auto to manual, the MC3000 series keypad replaces the forward/reverse button with Local/Remote.
The MC3000 industrial drives
The choice when your process control demands fast acceleration and response. Designed expressly for use where the motor control is an integral part of a process, the MC3000 is rated for constant torque applications but can easily be configured for variable torque applications. Most process control drives are designed for variable torque applications where the motor is driving a centrifugal fan or pump. As such, these drives are limited to 110% current for overload situations such as acceleration or responding to a feedback change.
The MC3000 is a true Constant Torque drive rated for 180% of rated current for 30 seconds and 150% for one minute; this allows faster response to system changes and the ability to apply the MC3000 to non-centrifugal applications such as compressors, conveyors and other "constant torque" loads.
The MC3000 is available in a power range of 1/4 to 150 HP (0.18 - 110 kW) and voltages ranging from 115 to 575 VAC.
